Air-supported structures



FIG. 1 is a side elevation view of air-supported structures combinationshowing my design and illustrating a cable net on the principalstructure,

FIG. 2 is a plan view of the air-supported structures in FIG. 1,

FIG. 3 is a front elevation view of the air-supported structures in FIG.1,

FIG. 4 is a rear elevation view of the principal air-_supportedstructure in FIG. 1,

FIGS. 5-11 inclusive, are transverse sectional views of theair-supported structure illustrating the sectional profile configurationof the air-supported structure at corresponding section lines in FIGS. 1and 2.

The two air-structure are illustrated in an inflated condition and areeach made of a suitable flexible plastic sheet or membrane. Theelongated principal structure is symmetrical about a verticle plane ofsymmetry passing through its longitudinal axis and has the sameconfiguration on opposite sides of the vertical plane of symmetry sothat an elevation view of one side illustrate the opposite side inFIG. 1. The smaller structure is bubble-shaped and is joined to the mainor principal structure through an enclosed passageway.

The ornamental design for air-supported structures, as shown anddescribed.
